PINK ALUMINUM OXIDE (PA)  
     
 
 
     
  Pink aluminum oxide, its hardness is close to, but toughness higher than that of WA. The abrasive tools made of it feature excellent durability and high processing clearness, which are suitable for the precision grinding of the measuring tools, lathe main shafts, instruments and apparatus parts threading work pieces and samplers.
